Lore

Once, people thought that imprisoning the Undead and hiding them away would solve the problem, so they created a towering bastille to contain them.

Off the coast of Drangleic is a lonely prison filled with Undead. It can be accessed by a ship that sets sail from No-Man's Wharf. The King sought to contains the curse by removing the afflicted, though it ultimately proved futil and the Kingdom has fallen. The now-Hollowed jailers and Royal Swordsmen continue to prevent the escape of the prisoners. At the heart of the prison though, lies a lost, forgotten Sinner.

Foes encountered here include:

Undead Jailor: The Undead Jailers of the Lost Bastille carry primitive weapons intended to instill fear and can even use pyromancy to burn escapees, and intruders, to a crisp. The Jailers are wrapped in bandages. What lies beneath? Have they been burned by their own flames, or are they hiding a darker secret?

Royal Swordsman: The Royal Swordsman were chosen from the bravest of King Vendrick's men, and provided them with the best armor available for the war against the Giants. However, very few survived the battles. While they may be no match for Giants, they still pose a threat when they attack you in numbers.

Undead Citizen: These Undead Citizens have been gathered up and exiled to the distant prison. For many their only crime was showing signs of the "Curse." But before you decry this injustice, face them in battle and see what horrors they are capable of…

Enhanced Undead: This deformed, unnatural creature must surely be the product of some serious misdeeds. Who created this monstrosity, and is it what they intended to make? It almost seems to be half-dragon, but, whatever it is, it has a mind of a Hollow.

Heide Knight (Spear): Whether Heide was a proper kingdom or not isn't clear, as it fell into the sea long ago. What is known is that the Way of Blue originated in Heide. Equipment from Heide still exists today, as well, which speaks tot he durability of the special allow used in its construction. If this knight truly is from the ancient land of Heide, is it possible that time distortion explains his presence?

Vorgel the Sinner (Dark Spirit): In a prison filled with sinners and innocents alike, Vorgel certainly has a special place. He stands watch of the Bastille Key. He wears the armor and dons the shield of a Royal Soldier; perhaps he is one of the wardens of this lost prison? What sins rest in this warrior's den?

Ruin Sentinels: The Ruin Sentinel has no physical form; it's merely a Soul haunting a large suit of armor. The Sentinels are the creations of the mysterious "jailer." There are three Sentinels here, with three names: Yahim, Alessia, and Ricce. Were those the names granted to the Sentinels by the jailer, or did they belong to the previous owners of these lost Souls?

Straid Dialogue
"So, how long was I sat petrified… Long enough for the old kingdom to have crumbled, I see. Long enough for Olaphis to rise, fall, and fade away, evidently. Why didn't anyone wake me sooner?! Heh heh…"
"Drangleic… I've never heard the name. Is that what they call this place now? Hah hah…Very good, very good indeed."
"The cursed ones were imprisoned within this land. Of course, you came of your own free will. Heh heh… The people feared the cursed ones like a plague. Some people would rather keep dreadful things out of sight, out of mind. In the end they swept them up and corralled them here. So very typical of meek minds, don't you think?"
"Once people became aware of their own frailty… They seized anybody they found undesirable, cursed or no, and impounded them here. Whoever posed even the slightest threat, was removed. All so that they could sleep better at night. They even turned the great Straid into a stone! Hah hah!"

Shalquoir Dialogue
"Once, people tried to round up the Undead and hide them away from the world. They thought that imprisoning the Undead would solve the problem. They created a towering bastille to contain them, but in the end, it did no good. The Lost Sinner lives deep within the bastille. The fool. Trying to light the First Flame…"
